1950-talets svenskar konfronterades aldrig direkt med det kalla kriget, utan mötte det i medierna. Populärkulturens berättelser hade en formande kraft. Trots att de handlade om mode, sport och skönhetstävlingar, bar de ändå stormaktkonfliktens signatur. Reportage om nylonstrumpor och kärleksliv laddades med politik och strukturerade tänkandet. En femtitalsberättelse visar hur ideologi och politi

Popular Abstract in Swedish Rovdjur påverkar strukturen och artsammansättningen i de flesta system. Både genom att äta upp bytesdjur och genom att inducera olika typer av försvar hos bytesdjuret kan rovdjur påverka andra organismer i systemet. Att undvika att bli upptäckt, och därmed sannolikt uppäten, av ett rovdjur är grundläggande för fortlevnaden hos alla bytesdjur. Under utvecklingens gång haPredator released chemical cues provide a valuable source of information to prey organisms that can be used to alter their behaviour in order to reduce predation risk. In this thesis, I have examined under what circumstances chemical cues may be used by prey, and if prey discriminate between different cues. I have also investigated the role of predator experience in prey ability to detect and resp

In Sub-Saharan Africa we find some of the highest levels of income inequality in the world. Nevertheless, we generally know very little about the historical development of inequality. In this paper we look at how inequality developed in colonial and post-colonial Botswana. We show that income inequality started rising in the 1940s and peaked in the mid-1970s about the time that the economy switche

The essays collected in the present publication deal with personality psychology viewed in a process perspective, termed perceptgenesis from the vantage point of perception and microgenesis when neuroscience is involved. The perceptgenetic approach was tried in Lund already in the middle of the 20th century. One fruitful field of application was clinical diagnostics defence mechanisms being a majo

An increasing number of studies have been focusing on the cognitive abilities and limitations of the designer during the design process, yet thus far only for the conceptual design phase. This paper deals with the embodiment design and detail design phases. We focus on the problem-solving process - strategies and basic steps - around the synthesis activity. Six experiments have been carried out, a

Multiple-input multiple-output (MIMO) systems operating at frequencies in the upper VHF and lower UHF region is attractive for peer-to-peer communication applications where robustness is of high importance, e.g., in tactical networks and emergency response systems. When designing and evaluating such systems, knowledge of realistic propagation conditions is required. This paper presents results fro

Stage models were prevalent in developmental psychology in the past, but have recently been subjected to much criticism. We propose “rehabilitation”, defining semiotic stage as a (not necessarily stable) period characterized by the clear establishment of a novel semiotic capacity, which may “dominate” the communication of the child at this stage, but does not replace capacities from previous

Under första terminen på kemiteknik-programmet läser teknologerna matematik, kemi och kemiteknik. Kemiteknik är ett helt nytt ämne för teknologerna jämfört med de övriga. Den beräkningsmässiga delen av kemitekniken läses under 2 läsperioder. Ett didaktiskt projekt[1] har utförts där teknologernas förståelse av grundläggande begrepp undersöktes med hjälp av intervjuer vid två tillfällen under kurse
